Abstract

The object of the invention is to provide an epoxy resin that is transparent and can be employed in dental fields for performing precise and transparent dental models that can be used in dental implants and in light curing materials, such as composite and polycarbonate materials. The transparent epoxy resin have to react to substance that allow to get away moisture and to strengthen chemical resistance, to improve transparency and impact strength, to reduce deformation under load, to increase abrasion resistance, and to improve environmental stress crack resistance and adhesivity. The grafted transparent epoxy resin can be used, as an example, by dental technicians to performing very precise and transparent dental models particularly helpful for building, as an example, crowns or bridges on dental implants having the possibilities to see the precise position of dental implants; or else building stump pin and inlay and onlay in, as an example, composite materials curing light and the transparent dental models allow the cross in every direction by the dental curing light.

Description

DESCRIPTION
TRANSPARENT EPOXY RESIN FOR PRECISE DENTAL MODELS
TECHNICAL FIELD
Transparent epoxy resin invention relates to resin that can be employed in dental field for performing teeth models to use in implantology, and by curing light materials.
In the operation of building dental models for implantology and for curing light materials it is very essential that models are very precise, rich in dental details, can be worked by hand and rotating instruments and, overall, are transparent to allow to see depth, essential by dental implants, and to allow to cross to curing light, essential by use of curing light materials.
Such precautions are necessary to prevent imperfect dental models for implantology and for curing lihgt materials such as may be caused opaque materials or transparent materials but very little precise, very moisture sensitivity.
Transparent epoxy resin allow to have dental models very transparent, very precise, very workable, very hard particularly right for performing dental models in dental implantology and dental curing light materials. BACKGROUND ART
The prior art : dental stone provided opaque dental models, very little precise, very little smooth and very little resistant to rotating instruments and little right for seeing, as an example, the position of dental implants in models or to make crossing dental curing light by dental curing light materials.
: acrylic resin provided transparent dental models but they are very little precise and very unstable dimensionally and then they can be used only as dental study models and not for performing dental models to work, as an example dental technicians cannot by its building crowns on dental implants.
DISCLOSURE OF INVENTION
In accordance with the present invention , we provide a transparent epoxy resin that is very transparent, is very dimensionally stable, is not moisture sensitivity and that maintains resin property for a long time.
Our improved transparent epoxy resin possesses the advantage that dental technicians can perform transparent dental models particularly helpful for building, as an example, crowns or bridge on dental implants having the possibility to see the precise position of dental implants; or else building stump pin and inlay and onlay in, as an example, composite materials curing light and the transparent dental models allow the cross in every direction by the dental curing light. Our present invention consisting of adding the vinyltrimethoxysilane to transparent epoxy resin to modifepoxy resin by grafting to the polymer backbone, equipping the polymer with pendant trimethoxysilyl groups that may be used as moisture-activated crosslinking sites. Benefits of Crosslinking
Improved transparency Higher maximum use temperature
Reduced deformation under load ( creep )
Improved chemical resistance
Superior environmental stress crack resistance
Increased abrasion resistance Improved impact strenght
Memory charactheristics ( for shrink film and tubing )
Applications
First, we have grafting ( reacting ) transparent epoxy resin to vinylmethoxysilane.
Second, we have storing the resin grafted before use for performing dental models.
The grafted resin is stable and can be shipped, handled, and stored, if properly packaged to exclude moisture for a long time. Third, when we have perform dental models we have making react the grafted resin to transparent resin catalysts. Fourth, the grafted resin produce a more fluidity of that resin that allows to get rich dental details from dental impressions. Fifth, the grafted epoxy transparent resin produce precise dental transparent models that also are very resistance to hands and rotating instruments for improved chemical resistance, reduced deformation under load (creep), superior environmental stress crack, increased abrasion resistance, improved impact strength, improved shrinkage, and, overall, improved transparency.
BRIEF DESCRIPTION OF DRAWINGS
FIG. 1 represents a container with transparent epoxy resin, FIG. 2 a bottle with viniltrimethoxysilane, and FIG. 3 a container with catalysts transparent epoxy resin. In next drawings FIG. 2 is pouring in FIG. 1.
FIG. 4 represents a container with transparent epoxy resin mixed to viniltrimethoxysilane, and FIG. 5 represents a measuring vessel.
FIG. 4 and FIG. 3 are pouring in FIG. 5.
FIG. 6 represents a measuring vessel with transparent epoxy resin mixed to viniltrimethoxysilane and catalysts transparent epoxy resin,
FIG. 7 represents an impression tray with silicon impression, FIG. 8 represents a transparent dental model.
FIG. 6 is pouring on FIG. 7 and FIG. 8 is the finished result
(transparent dental model).
BEST MODE FOR CARRYING OUT THE INVENTION First of all we have pouring the vinyltrimethoxysilane, in liquid form, by appropriate dose on transparent epoxy basic resin, in fluid form, and mixing for a short time by a carve until to make all homogeneous. Then we can pouring the transparent epoxy basic resin grafted (by vinyltrimethoxysilane) and the transparent epoxy catalysts resin, in fluid form, on a measuring vessel in according to recommended ratios, and mixing for a short time by a carve. After we pour the contents of measuring vessel on impression tray with silicon, or other material, teeth impression and we awaiting for twelve hours that resin hardens.
The final result is a very precise transparent dental model. It is also possible performing mixed opaque-transparent dental models using polyurethanic resin and this transparent epoxy resin. In that case we have pouring before basic and catalysts polyurethanic resin on impression tray with silicon, or other material, teeth impression and we awaiting for hardening and after we have pouring basic and catalysts transparent epoxy resin and awaiting for hardening twelve hours. The final result is a very precise opaque-transparent dental model.

Claims
